WILLIAM N. SPRINGER, OF SOUTH BEND, INDIANA, ASSIGNOR TO OLIVER CI-IILLED PLOW WORKS, OF SOUTH BEND, INDIANA.

GANG-PLOW.

Specification of Letters Patent.

Patented June 16, 1914.

To all whom it may concern:

Be it known that I, WILLIAM N. SPRINGER, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Gan-g- Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in plows and more particularly to means for adj ustably connecting the standard with the beam,one objectof the invention being to provide simple and efficient means for adjusting the soil-engaging member or plow bottom in a manner to raise or lower the point thereof and thus adjust the pitch or suction of the plow.

With this and other objects in view, the.

invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a side elevation of a plow showing the application of my improvements; Fig. 2 is a plan view, Fig. 3 is a side elevation partly broken away and partly in section, and Figs. 4, 5 and 6 are detail views.

1 represents a plow beam comprising two sections or members 23 spaced apart and held rigid with respect to each other, the rear end portion of the beam member 2 being bent toward the beam member 3 but spaced therefrom sufliciently for the accommodation of the upper portion of a plow standard 4 and plates 55, said standard having secured to its lower end, a soil-engaging member or plow bottom 6. The plates 5 are secured to the inner sides of the beam members by means of suitable bolts and the upper portion of the standard enters between these plates. The plates 5 are provided at their forward ends with depending lugs 7 between which the forward projecting arm 8 of the standard 4 enters and to which said standard is connected by means of a break pin 9.

The rear portion of the standard 4 is constructed to project somewhat above the plow beam members and is provided with a slot 10. A bolt 11 passes transversely through the parallel beam members 23 and plates 5 near the rear ends of the same and also through the slot 10 in the standard.

A post 12 is loosely mounted at its lower end upon the bolt 11 and projects upwardly through a lateral recess 12 in the standard 4 and terminates above the upper end of the latter, and said post is provided at its upper end with a toothed segment 13. A pin 14 projects laterally from the segment 13 at the upper end of the post 12 and on this pin, a cam lever 15 is mounted and adapted to engage the upper end of the plow standard. A latch lever 16 is bifurcated at one end to embrace the cam lever and is pivotally attached to the latter at 17 said latch lever being provided with a tooth 18 to engage the toothed segment 14. The cam lever 15 is provided with a handle 19 having a socketed boss 20 to receive one end of a spring 21 and the latch lever is made with a handle 22 having asocketed boss 23 to receive the other end of said spring,the latter thus serving to retain the tooth of the latch lever in engagement with the toothed segment.

From the construction and arrangement of parts above described it will be apparent that if the cam lever be turned in a forward direction, engagement of said cam lever with the upper end of the standard will cause the rear portion of the latter to be depressed and swung over the pivotal connection of the forwardly projecting standard arm 8 with the pin 9,thus tilting the point of the soil-engaging member upwardly and adjusting the pitch or suction of the plow. It is evident that if the cam lever be moved rearwardly, the reverse of the above adjustment will be efiected.

WVith the use of my improvements, the pitch or suction of the plow may be easily and quickly adjusted and locked at any desired adjustment. Should the soil-engaging member encounter any unyielding obstruction, the pin 9 will break and the standard and soil-engaging member will swing backwardly, on the bolt 11,-the suction adjusting devices moving with the standard.

Slight changes might be made in the details of construction of my improvements without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. The combination with a plow beam, a standard, a soil-engaging member secured to the latter, and means pivotally connecting the forward portion of the standard with the beam, of a pOSt pivotally connected with the beam, a cam pivotally connected with the post and adapted to engage the rear portion of the standard for tilting said standard and the soil-engaging member to adjust the pitch of the latter, means for operating said cam, and means for locking said cam at different adjustments.

2. The combination with a plow beam, a

standard pivotally connected therewith, and a soil-engaging member secured to the standard, of a post pivotally connected with the beam, a cam lever pivotally connected with the post and adapted to engage the upper portion of the standard, a toothed segment, and a latch pivoted to the cam lever and adapted to engage the segment.

3. The combination with a plow beam, of a standard pivotally connected with the beam and having a vertical slot in rear of said pivotal connection, a soil-engaging member secured to said standard, a bolt passing transversely through the beam and through the vertical slot in the standard, a post mounted on said bolt, a toothed segment at the upper end of the post, a cam lever pi otally connected with said post and engaging the upper end of the standard, and a latch lever carried by the cam lever and engaging the toothed segment.

l. The combination with a plow beam, of a standard having a forwardly projecting arm, a break pin connecting said standard arm with the beam, a soil-engaging member secured to the standard, said standard having a slot in its rear portion, a bolt passing transversely through the beam and through the slot in the standard, a post mounted on said bolt, a cam lever mounted on said post and engaging the upper end of the standard, and means for locking the cam lever at any desired adjustment.
